[Help] How to Load 2 or more HTML file?

hai. i have project speedometer with skin based html. i have problem about the html. this problem i cannot load 2 or more html on my project. in console ingame only show send_nui_message: resource speedometer has no ui frame.

i try to delete 1 html on __resource ui_page. and its normal again.

so how to make my project can load 2 or more html. because this html is skin for my speedometer

You cant use the ui_page more than once. You are gonna have to write code to load other html files and embed it into the 1 html you load or use a interface compiler to compile it down into 1 html file and js / css files.

ok i will try to make 1 html to load other html
